Alan Rickman not bothered about going nude

Cameron Diaz and Colin Firth take part in a modern reboot of the 1966 British caper comedy starring Michael Caine and Shirley MacLaine. British art curator Harry Deane (Firth) has devised a finely-crafted scheme to con England's richest man and avid art collector, Lionel Shabandar (Alan Rickman), into purchasing a fake Monet painting. In order to bait his buyer, he recruits a Texas rodeo queen (played by Diaz) to cross the pond and pose as a woman whose grandfather liberated the painting at the end of WWII. While the new accomplice seems perfect, Harry himself becomes enraptured with her, causing his plan to take a series of wrong turns.

Alan Rickman didn't worry about people spotting him filming nude scenes in public for 'Gambit'.

The veteran actor stripped off for scenes in London landmark building The Gherkin - which has floor-to-ceiling windows - but never asked for the set to be closed to prevent passers-by from catching a glimpse of him naked.

Director Michael Hoffman said: ''I did think it would be very hard to have an open set in an all-glass [building by architect Norman Foster]. But he didn't ask for us to close it off - he was very brave.''

Alan, 66, joked about the experience, telling the Daily Star newspaper: ''Sometimes you can get costumes you can't bear wearing. So it was a relief not to have to say, 'I don't like this costume.'''

The film - a remake about an art curator who takes revenge on his boss by selling him a fake Monet painting - also stars Cameron Diaz and Colin Firth, and Michael added the latter had the film crew in stitches with his unintentionally hilarious behaviour on set.

He said: ''Colin is more unintentionally funny. Cameron you're always laughing along with. Sometimes with Colin you get to laugh at him.''

Speaking about a scene with a real-live lion, he added: ''The stuff that always made me laugh was the lion, who was at times more interested in the art on the wall than he was in Colin. That was a little embarrassing for Colin because he was supposed to be under threat from this lion and it was literally looking at these pictures behind him.''

'Gambit', with a screenplay by Joel and Ethan Cohen, is in cinemas now.
